Since I need to report a crash, I need to get a gdb stack trace. That
means I need to compile with debug (with symbols). How do I do that?
>From the gcc manpage:
-g Produce debugging information in the operating system's native format
(stabs, COFF, XCOFF, or DWARF 2). GDB can work with this debugging
information.
So add -g to your CFLAGS. (Set CFLAGS="-g" plus whatever other CFLAGS you
use before compiling.) Note that various optimizations can make debugging
difficult, of course. See the manpage for additional -g<otherstuff> flags.
Finally (and in general), note that symbols may be stripped by the
build/make script. I'm not sure if pan's does or not, but at the
./configure step, you can try ./configure --help and see what it spits
out. It's likely you can add a debug option there that will take care of
the gcc -g as well as any stripping.
Actually, after doing a straight configure, I saw that CFLAGS and
CXXFLAGS were both set to:
-g -O2
so I doubt that it strips the symbols (what would be the point then of
the -g?). I get the same crash whether I compile pan myself or use the
pre-built SUSE 10.1 pan 0.99 binary (pointed to from the pan web site).
I do NOT get the crash when I use a different news server. So it is
something in the newsgroup list of this particular server
(newsgroups.comcast.net, actually giganews) which is triggering the bug.
Now if only I could figure out what the offending group name is, maybe I
could come up with a patch, or at least a useful bug report.
